We have already spoken, in the first chapter, on the identities existing in all the religions of the world, and we have seen that out of a study of t… - Annie Besant

Long before the discovery of radium led to the recognition of the electron as the common constituent of all the bodies previously described as chemical elements, the minute particles of matter in question had been identified with the cathode rays observed in Sir William Crookes' vacuum tubes. When an electric current is passed through a tube from which the air (or other gas it may contain) has been almost entirely exhausted, a luminous glow pervades the tube manifestly emanating from the cathode or negative pole of the circuit. This effect was studied by Sir William Crookes very profoundly. Among other characteristics it was found that, if a minute windmill was set up in the tube before it was exhausted, the cathode ray caused the vanes to revolve, thus suggesting the idea that they consisted of actual particles driven against the vanes; the ray being thus evidently something more than a mere luminous effect. Here was a mechanical energy to be explained, and at the first glance it seemed difficult to reconcile the facts observed with the idea creeping into favour, that the particles, already invested with the name "electron," were atoms of electricity pure and simple. Electricity was found, or certain eminent physicists thought they had found, that electricity per se had inertia. So the windmills in the Crookes' vacuum tubes were supposed to be moved by the impact of electric atoms.

The subject of the unfolding of conscious­ness in the beings whose field of evolution is a solar system is one of considerable difficulty; none of us may at present hope to do more than master a small portion of its complexity, but it may be possible to study it in such fashion as may fill up some of the gaps in our thinking, and as may yield us a fairly clear outline to guide our future work.

He has then realised the peace of the Master, the one who is utterly master of his vehicles, and therefore master of life and death. Capable of receiving into them the tumult of the world and of reducing it to harmony; capable of feeling through them the suffer­ings of others, but not sufferings of his own; he stands apart from, beyond, all storms.
